Slag/dross and leaching residue are produced from the process of metal extraction. The commonly-seen slag/dross/residue includes copper dross, lead dross, tin slag, zinc leaching residue, antimony/arsenic dross, cadmium residue/cake, sulfur residue/cake, vanadium slag, nickel slag, iron tailing and iron bearing red-mud waste.

Due to its low concentration, it may be not profitable to extract single metal, so it is usually landfilled. However, the increasing awareness of environment protection requires a safer and better treatment method. Comprehensive recovery of these slag/dross has been emphasized with greater attention.
